Genes affected

POGZ (HGNC:18801): (pogo transposable element derived with ZNF domain) The protein encoded by this gene appears to be a zinc finger protein containing a transposase domain at the C-terminus. This protein was found to interact with the transcription factor SP1 in a yeast two-hybrid system. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 53 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406271-TG-T is Pathogenic according to our data. Variant chr1-151406271-TG-T is described in ClinVar as [Pathogenic]. Clinvar id is 3255024.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr1-151406271-TG-T is described in Lovd as [Pathogenic].

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with White-Sutton syndrome (MIM#616364). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0204 - Variant is predicted to result in a truncated protein (premature termination codon is NOT located at least 54 nucleotides upstream of the final exon-exon junction) with at least 1/3 of the protein sequence affected. (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0600 - Variant truncates the annotated DDE superfamily endonuclease and Tc5 transposase DNA-binding domains (DECIPHER). (I) 0701 - Other downstream truncating variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (DECIPHER). (SP) 0802 - This variant has moderate previous evidence of pathogenicity in an unrelated individual. This variant has been observed as de novo in an individual with a POGZ-related neurodevelopmental disorder (PMID: 35052493). (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) (by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
